Rose plant named ‘POULshrimp’

ABSTRACT

A new miniature rose which has abundant, orange-red flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

BOTANICAL CLASSIFICATION

Rosa hybrida.

VARIETY DENOMINATION

‘POULshrimp’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety ofminiature rose plant which originated from a controlled crossing between‘POULege’, a rose by the same inventors, described and illustrated inU.S. Plant patent application Ser. No. 09/282,073 dated Mar. 29, 1999;and ‘POULvic’, a rose by the same inventors, described and illustratedin U.S. Plant Pat. No. 8,012 issued on Oct. 27, 1994. The two parentswere crossed during the summer of 1990 and the resulting seeds wereplanted in a controlled environment in Fredensborg, Denmark. The newvariety is named ‘POULshrimp’.

The new rose may be distinguished from its seed parent, ‘POULege’, bythe following combination of characteristics:

1. ‘POULshrimp’ has bright orange-red blooms, whereas the ‘POULege’ hassalmon-orange blooms.

2. ‘POULshrimp’ is a miniature garden rose, whereas ‘POULege’ is afloribunda rose.

3. ‘POULshrimp’ exhibits more compact and even and growth than‘POULege’.

The new variety may be distinguished from its pollen parent, ‘POULvic’by the following combination of characteristics:

1. ‘POULshrimp’ has bright orange-red blooms, whereas ‘POULvic’ has redblooms.

2. ‘POULshrimp’ exhibits less flowers per stem when compared to‘POULvic’.

3. ‘POULshrimp’ is a larger plant in height and width than ‘POULvic’.

The objective of the hybridization of this rose variety was to create anew and distinct variety for garden use with unique qualities, such as:

1. Uniform and abundant flowers;

2. Vigorous, but compact growth;

3. Disease resistance.

This combination of qualities is not present in previously availablecommercial cultivars of this type and distinguish ‘POULshrimp’ from allother varieties of which we are aware.

As part of their rose development program, L. Pernille Olesen and MogensN. Olesen germinated the seeds from the aforementioned hybridizationduring winter 1990 and conducted evaluations on the resulting seedlingsin a controlled environment in Fredensborg, Denmark.

‘POULshrimp’ was selected in the spring of 1991 by the inventors as asingle plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘POULshrimp’ by traditional budding and rootedcuttings was first done by L. Pernille and Mogens N. Olesen in theirnursery in Fredensborg, Denmark in summer 1991. This initial and othersubsequent asexual propagations conducted in controlled environmentshave demonstrated that the characteristics of ‘POULshrimp’ are true totype and are transmitted from one generation to the next.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustration shows as true as is reasonablypossible to obtain in color photographs of this type the variety rose‘POULshrimp’. Specifically illustrated in SHEET 1 include ‘POULshrimp's’foliage, flower buds, partially opened buds, and numerous open blooms.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘POULshrimp’, as observed in its HalfMoon Bay, Calif. Oregon, on plants aged sixteen weeks. Root developmentfor the observed plant typically takes 8 to 10 weeks. Color referencesare made using The Royal Horticultural Society (London, England) ColourChart, 1995, except where common terms of color are used. For acomparison, several physical characteristics of the rose variety‘POULrouge’, a rose variety from the same inventors described andillustrated in U.S. Plant Pat. No. 9,687 issued on Nov. 12, 1996 arecompared to ‘POULshrimp’ in Chart 1.
